Math was never exactly our strong suit in school.

That’s unfortunate because, as you know by now, there can be a substantial amount of math involved in hot rodding, racing, and general automotive mechanics. Luckily for folks like us, there are a number of automotive calculators around to help make this motorhead math simpler. Here, we’re going to share 13 essential calculators you should know about to make some of your future projects simpler and quicker.

We only included 13 because that’s as high as we can count. We’re just that bad at math around here (well, maybe not that bad). There are other automotive calculators available, but these are the ones we felt would have the most appeal. You may want to save or bookmark this page for quick access. And while you’re at it, you might want to check out our 13 Key Automotive Formulas Every Gearhead Should Know post, too.
